Green Manzanita Greenleaf Manzanita
Arctostaphylos patula
Ericaceae · broadleaf · native
You recognize Greenleaf Manzanita by its smooth reddish-brown exfoliating bark and bright green, urn-shaped leaves on exposed coniferous forest slopes throughout the Pacific Northwest. This widespread native thrives at moderate to high elevations where cool temperatures and rocky soil match its precise ecological niche.
Greenleaf Manzanita grows 7 feet tall in full sun with moderate water needs and high drought tolerance once established (zones 5a-8b). It prefers well-drained, adaptable soils with medium CaCO3 tolerance and spreads slowly. Pinkish-white flowers appear in late spring; resprout ability aids recovery from disturbance. Monitor for the same diseases affecting arctostaphylos: leaf spot, rust, and phytophthora dieback are common in humid summers.
